{{short description|Education technology specification by IMS Global Learning Consortium}}
'''Learning Tools Interoperability''' ('''LTI''') is an education technology specification developed by the 1EdTech ([[IMS Global Learning Consortium]] at the time of creation). It specifies a method for a learning system to invoke and to communicate with external systems.<ref name="IMS">{{cite web|url=http://www.imsglobal.org/toolsinteroperability2.cfm |title=Learning Tools Interoperability |publisher=IMS Global |date= |accessdate=2015-09-07}}</ref> In the current version of the specification, v1.3, this is done using [[OAuth2]], [[OpenID Connect]], and [[JSON Web Token]]s. For example, a [[Learning Management System]] (LMS) may use LTI to host course content and tools provided by external, third-party systems on a [[World Wide Web|web]] site, without requiring a learner to log in separately on the external systems, with information about the learner and the learning context shared by the LMS with the external systems.
